3.3.2 AMX0.2CN&Output&Connections&
!
The!AMX0.2CN!is!should!be!connected!as!follows…!
!
• XLR!Connector:!The!XLR!output!has!a!low!impedance!(600ohm)!drive!and!can!be!
connected!to!most!ProLAudio,!MI,!Prosumer!or!Consumer!equipment.!The!
sensitivity!switch!will!set!the!nominal!output!to!+4dBu!(ProAudio),!L2dBu!
(MI/Prosumer),!or!L8dBu!(Consumer)!levels.!
!
• RCA!Connectors:!These!are!paired/mono!outputs!with!a!fixed!gain!(L8dBu!
nominal)!and!10k!ohm!output!impedance.!The!RCA!outputs!provide!a!simple!and!
fast!connection!for!Consumer!equipment!such!as!MP3!players!and!Laptops!over!
short!distances.!
!
NOTE:!The!AMX0.2CN!internal!regulator!is!a!compact!size!(to!suit!the!wall!mount!
application).!This!places!a!strict!limit!on!the!impedance!of!the!load!it!can!drive.!!The!
AMX0.2CN!can!happily!drive!a!10kohm!load!at!+24dBu!and!a!600ohm!load!at!+22dBu,!
but!loads!of!less!than!300ohm!will!pull!the!device!out!of!regulation.!Similarly,!driving!
the!interface!into!a!clip!condition!will!cause!overLcurrent!and!pull!the!device!out!of!
regulation.!In!both!situations,!the!likely!effect!is!to!reset!the!interface.!
